348 Fieldbus control with fieldbus adapter
Fieldbus reference scaling
Fieldbus references REF1 and REF2 are scaled for the DCU profile as shown in the
following table.
Note:
Any correction of the reference (see section
on page
) is applied before scaling.
Note:
The settings of parameters
have no
effect on the reference scaling.
Reference handling
Reference handling is the same for the ABB drives profile (embedded fieldbus) and
DCU profile. See section
Actual value scaling
The scaling of the integers sent to the master as Actual values depends on the
selected function. See chapter
on page
